Main factors to be considered when buying a house or choosing a building:
Light: From the perspective of light, the floor is naturally not suitable for being too low, and the sunlight of low-rise buildings will be blocked by surrounding buildings. But the floor is too high and the angle is wrong, which will also affect the sunlight.
Vision: Needless to say, the higher the floor, the better the vision. But the sun shines directly on the roof of the top building, and it will be very hot in summer, and multi-storey buildings will be relatively better.
Noise: There are many noise sources in the city, which will affect people's health, make people unable to eat and sleep, and reduce learning efficiency. The lower the floor, the more noise it absorbs. But it is better if there are trees, sound insulation boards and other objects that absorb sound waves around low-rise buildings. And the sound will be uploaded, and high-rise buildings will not be spared. Generally speaking, the noise of buildings above 20 floors has little effect.
Dust: It is generally believed that the 8- 10 layer is a dust layer, and the dust will be suspended at this height. In fact, the ash layer cannot be generalized.
Floor height: From the architectural form, multi-storey generally refers to buildings with six or seven floors, and high-rise refers to buildings with more than seven floors. Compared with high-rise buildings, multi-storey buildings have the advantages of good lighting, good ventilation and low living cost. With the increasing shortage of land resources and the improvement of people's requirements for living comfort, high-rise buildings have entered people's lives; In recent years, it has been loved by more and more young people and has gradually become a trend of life. This paper compares the characteristics of high-rise and multi-storey buildings from the aspects of building quality, usable area, vision, property management and structural pattern. We can summarize as follows:
Building quality: Generally speaking, the building standards and quality of high-rise buildings are higher than those of multi-storey buildings. Ordinary multi-storey residential buildings are generally brick-concrete structures, while high-rise residential buildings are cast-in-place reinforced concrete, with deep and solid foundation, thick wall, no water seepage and better seismic performance than multi-storey buildings, so the whole building will not sink and deform; And the depreciation period is long.
Vision: High-rise buildings have wider vision, better air quality and less noise; Strong natural wind, good lighting and long sunshine time.
Usable area: The occupancy rate of high-rise buildings is lower than that of multi-storeys, that is, the indoor construction area of high-rise buildings is lower than that of multi-storeys. High-rise residential buildings have elevator waiting rooms and basements. And there are many public areas to be shared, so the actual occupancy rate is low.
Property management: most high-rise property management is relatively perfect, but the property management fee is higher than that of multi-storey property management.
